Some common problems of the computer, some common problems and solutions of the computer

The motherboard is a key component of the entire computer and plays a vital role in the computer. If the motherboard fails, it will affect the whole motherboard.

Common fault 1: No display is displayed when the computer is turned on.

There is no display when the computer is turned on, and the first thing we need to check is the BIOS. The BIOS of the motherboard stores important hardware data, and the BIOS is also a relatively fragile part of the motherboard, which is extremely vulnerable to damage, and once damaged, the system will not be able to operate.

Class failures are generally caused by the destruction of the motherboard BIOS by CIH viruses (of course, it is not excluded that the motherboard itself is faulty and the system cannot be operated. ）。Generally, all the data in the hard disk will be lost after the BIOS is damaged by the virus, so we can judge whether the BIOS is damaged by detecting whether the hard disk data is intact

1.Because there is a problem with the motherboard expansion slot or expansion card, the motherboard does not respond and does not display when the expansion card such as a sound card is plugged in.

2.If the CPU frequency set in the CMOS is not the same for the jumper-free motherboard, it may cause a no-display failure, which can be solved by clearing the CMOS. Clear the CMOS jumper is generally near the lithium battery of the motherboard, its default position is generally short circuit, as long as it is changed to short circuit for a few seconds to solve the problem, for the old motherboard, if the user can not find the jumper, as long as the battery is removed, after the boot display enters the CMOS setting, then shut down, the battery up also achieves the purpose of CMOS discharge.

1.Memory Failure: Turn on the computer, automatically restart from time to time, or the computer beeps or the system is not running.

2.Graphics card failure: During the use of the computer, the sound is very normal, the monitor suddenly does not display, and sometimes even the screen is blurred, which should be considered.

Fault: During the use of the computer, it suddenly fails to turn on, and the monitor does not display, and the problem of the graphics card is ruled out, then there is.

4.Hard disk failure: The operating system is normal, but the opening of the drive letter is very slow, or it cannot be opened at all, or the disk is not scanned.

5.Sound card malfunction: It is also very common for a computer to have a certain software installed and suddenly there is no sound, usually the software.

Frequently Asked Questions Crash Restart.

Reinstall the driver for the sound card.
